Wires are laid geometrically to form strands, each composed of two or more wires. Breaking these strand configurations into several classifications is the basis for identifying wire rope.

The individual wires that form strands are most commonly available in high-carbon steel, generally supplied in an uncoated, or "bright" finish. Zinc coated, or "Galvanized" rope is available in some sizes and carries a nominal strength of 10% below that of a bright rope. On special request, wire rope can be drawn-galvanized, offering the same nominal strength as a bright rope.

A steel center rope yields a higher strength along with the ability to resist crushing Steel cores are required when the environment exceeds 180Â°(F)
